This study aimed to investigate the effect of nanoparticles and non-nanoparticles of titanium dioxide on germination indices of Echinacea under salinity stress. Experimental treatments included nano and bulk particles of titanium dioxide at concentrations of 0, 10, 50, 100 and 150 mg/l and salinity stress from NaCl at levels of 0, -3, -6 and -9 bar. The results showed that Echinacea is sensitive to high salinity stress levels (-6 and -9 bar). The use of nano and non-nano titanium dioxide treatment improved some traits under severe salinity stress. The germination percentage did not occur at salinity levels of -6 and -9 bar, but the addition of nano titanium dioxide with a concentration of 150 mg/l and 50 mg/l non-nano increased germination by 50.6%. Application of nano titanium dioxide increased the seedling weight in control by 1.28 mg to 4.26 mg in the treatment of 150 mg/l nanoparticles. The application of nano and bulk titanium dioxide could significantly reduce the negative effect of high salinity stress levels. This can be a valuable and hopeful solution to solve the problem of salinity stress in Echinacea.

Strigolactone acts with other plant hormones to influence shoot architecture by suppressing axiliary bud outgrowth. The exogenous application of synthetic analogues of strigolactone, such as GR24, have been investigated as a way to manage plant architecture in a number of crops. In this study we test whether GR24 can be used to supress bud outgrowth in clonal propagules of tea tree (Melaleuca alternifolia) in order to retain a “single stem” form desirable for machine planting. GR24 was applied to decapitated rooted cuttings of tea tree at two rates (0.5 mg L-1 and 1.5 mg L-1), with and without auxin. By 21 days post-treatment, GR24 at both rates had significantly (p<0.05), reduced the mean number of axiliary buds (5.7 ± 0.4 and 5.5 ± 0.3 buds respectively) compared to decapitated untreated control plants (8.9 ± 0.6 buds). Suppression of buds was significantly higher again when auxin was applied in conjunction with GR24. Nonetheless, no exogenous hormone treatment was as effective at suppressing bud outgrowth as the apical dominance that occurred in intact control plants (1.1 ± 0.4 buds).

Light-reflecting covers can help plant development in shaded environments, improving growing conditions in small residential spaces, encouraging the practice of small cultivations of food and ornamental species. Thus, the objective of this work was to evaluate the effect of reflective bench covers on the growth and development of different cultivars of basil, in pot and shaded environment. The treatments consisted of three reflective materials (aluminum thermal reflective mesh, shiny red and white coating on laminates), arranged on the cultivation benches, and two basil cultivars (green and purple). After 22 days under these environments, the number of leaves and nodes, stem diameter, plant height, relative chlorophyll content, fresh and dry masses of the aerial and roots parts were determined. The highest value of reflective photosynthetically active radiation was shown when using white laminate, followed by the red laminate and thermal reflective mesh. The green basil varieties showed higher values for number of leaves, stem diameter, plant height, fresh shoot weight and number of nodes, compared to the purple variety; however, in relation to the relative chlorophyll content, the purple variety was superior. The bright white and red laminate covers positively influence environmental conditions, increasing the reflectance of photosynthetically active radiation, and the development of basil plants in conditions of greater shading.

Salicylic acid (SA) and ferulic acid (FA) are considered phenolic compounds that act as elicitors due to their regulatory functions on plant growth, development, metabolic and physiological responses in plants. The aim of this research was to evaluate the effect of SA and FA on growth, fruit quality and synthesis of secondary metabolites in tomato (Solanum lycopersicum cultivar Santa Clara). The experiment was conducted in pots in a greenhouse. The application of SA and FA was performed at concentration of 1.0 mmol L-1 alone and in combination, with water treated plants as control. Exogenous application of SA and FA either alone or in combination (SA + FA) resulted in increases in biomass accumulation and chlorophyll contents in tomato plant; and soluble sugar, total polyphenol, flavonoids, lycopene and β-carotene contents in fruits. It was concluded that application of SA and FA resulted in higher production and concentration of secondary compounds in tomato.

Veronica dahurica Steven (family Scrophulariaceae) is an ornamental plant from Korea. The aim of the present study was to produce multiple-branched plants by using 6-benzylaminopurine (BA) spray application at several time intervals after pinching. All 10 cm long plants were sprayed with 0, 500, 1000, and 2000 mg·L-1 BA at 0, 7, and 14 days after pinching. Growth characteristics were examined 10 weeks after pinching and flowering time was recorded. The number of branches was highest in the group sprayed with 1000 mg·L-1 BA at 0 d after pinching. The greatest plant height was observed in the group treated with 1000 mg·L-1 BA 14 d after pinching and the minimum plant height was observed in the group sprayed with 500 mg·L-1 BA at 0 d after pinching. The groups sprayed with higher BA concentrations and with longer intervals between pinching and spraying showed greater delay in the time to first flower. The flower length was decreased in the pinched and BA-treated group compared with the control. Thus, BA application and pinching could promote multiple branch induction and control flowering time in V. dahurica Steven.

Capsicum plant species are globally cultivated in warm and temperate regions, being important for agro-economic, biological and cultural aspects. While their worldwide spread and their ability of cross-pollination to easily hybridize play an important role in the formation of numerous species and varieties but also create confusion for their classification. For this reason, the categorization of species and varieties is complex and several methods have been used to evaluate pepper plant origin and evolution. Therefore, the objectives of this study were to compare a wild pepper (Capsicum chacoense) with other two domesticated cultivars belonging to different species such as Capsicum annuum and C. baccatum and draw conclusions about their origins using different approaches. For this purpose three methodologies have been used and compared: the comparison of their fruits volatile organic compounds (VOCs) emissions , their capsaicin and dihydrocapsaicin content and the leaves proteomic profiles. The VOCs analysis has been conducted by a time-of-flight mass spectrometry (ToF-MS) with an innovative approach to better identify all the compounds detected, in particular using two different ionization agents (H3O+ and NO+) to better identify all the compounds detected. The VOCs and pungency analyses were then used to build back propagation neural networks (BPNN) and a Random Tree classifier to conduct a multivariate analysis and evaluate the most species-specific volatiles. The outcomes appeared to be a most accurate approach with respect to the traditional varieties descriptors used for peppers discrimination. The BPNN led to the identification of several putative volatiles as good candidates for the recognition of these species or significant nodes in a decision learning tool. Finally, protein profiles have been obtained by SDS-PAGE analysis on the leaves to perform a fast proteomic comparison among the species. The protein profiles showed the C. baccatum and C. chacoense were more similar to the domesticated pepper C. annuum.

‘Patharnakh’ (PN) (Pyrus pyrifolia Burm. Nakai) and ‘Punjab Beauty’ (PB) [Pyrus communis L. × Pyrus pyrifolia Burm. (Nakai)] are leading low-chill pear cultivars of subtropics of India. Diurnal temperature and relative humidity during fruit harvest period is high which considerably affect the shelf life of fruits. Fruits of ‘PN’ and ‘PB’ pear harvested at physiological maturity were stored for 12 days at ambient temperature and effects of storage temperature on physical and qualitative parameters were studied. Both cultivars showed reduction in fruit weight and firmness, reducing sugars, sucrose, starch and pectin content. However, total soluble solids and juice acid content increased during storage. Sucrose synthase activity and sucrose content showed significant positive correlation in ‘PN’ cultivar. Activities of fruit softening enzymes such as polygalacturonase (PG) and cellulase was enhanced; whereas, pectinmethylesterase (PME) was reduced during storage. Fruit firmness was negatively correlated with PG in both the cultivars. In ‘PN’ cultivar, fruit firmness was positively correlated with cellulase and negatively with PME enzyme but reverse trend was observed in ‘PB’ cultivar. Fruit minerals content didn’t show any substantial disparities in both the cultivars during storage. ‘Patharnakh’ and ‘Punjab Beauty’ fruits maintain desirable quality parameters up to 6-9 days and 3-6 days, respectively, during storage at ambient conditions.

Cultivation of Corylus avellana L. in Turkey is performed generally in the northern regions where it is an important source of livelihood for the local farmers. More than 70% of world hazelnut production is supplied by Turkey, but compared with other countries, Turkey’s hazelnut production area is quite narrow. In this study was aimed to develop an effective in vitro production for seven local cultivars of C. avellana. Therefore, WPM medium supplemented with 6-Benzylaminopurine (BAP) was modified by using single or in combination of Fe-EDDHA, AgNO3, H3BO3, charcoal and gibberellic acid. In all varieties, the best regeneration rates varying between 68% and 94% were obtained from WPM medium supplemented with 4.4 µM BAP, 27.8 µM Fe-EDDHA and 10g/L Charcoal. Genetic stability of shoots derived from meristem culture using the best medium was analysed using ISSR primers, when the gel images of the PCR products were examined, no polymorphic band was observed in samples collected from seven provinces, and the genetic stability was determined as 100%.

Knowledge of the pattern of trait variation among accessions, and the trait profiles of the accessions is crucial for improvement of a crop. Twenty-one Amaranthus accessions were evaluated in 2018 and 2019 to investigate the extent of genotypic diversity among the amaranth accessions and their trait profiles. Data were subjected to analysis of variance, and correlation and principal component analyses. Taking stem weight (SWT) as the yield, the accession × yield-trait combination (GYT) biplot was employed to investigate the trait profiles of the accessions. Accession, year, and accession × year mean squares were significant (P≤0.05/0.01) for most of the measured traits. The first three principal components explained 88.18% of observable variation among the accessions and identified plant height (PHT), number of leaves per plant (NOL), and root weight (RWT) as the major contributors. Significant (P≤0.01) correlation was observed in the association of SWT with NOL, TBM, and RWT. Accessions NGB00019 and NGB00061 were associated with the sector containing all the YT combinations considered. However, NGB00019 was identified as the best combiner of yield with other traits. Further studies involving more traits should determine the trait profiles of the remaining accessions.

Accessions NGB00019 and NGB00061 were associated with the sector containing all the YT combinations considered. However, NGB00019 was identified as the best combiner of yield with other traits. Further studies involving more traits should determine the trait profiles of the remaining accessions.","PeriodicalId":7339,"journal":{"name":"Advances in horticultural science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70128586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
